APPARATUS FOR STORAGE OF'GASES.

SPECIFICATION forming part of Letters Patent No. 727,609, dated May 12,1903. Application filed May 24, 1901. Serial No. 61,726. (No model.)

To all whom it may concern:

Be it known that I, EDMOND FOUOHE, a citizen of France, residing atParis, France, have invented certain new and useful Improvements inApparatus for the Storage of Gases, of which the following is aspecification.

The object of my invention is to provide a receptacle for the storage ofexplosive or inflammable gases and such a filling therefor that in theevent of an explosion or the ignition of a portion of the gas only asmall volume will be affected, whereby danger from explosion is avoided.

In the drawings forming part of this specification, Figure 1 is asection of my improved receptacle. Fig. 2 is a view showing one form ofthe porous substance used therein.

A is the receptacle, which is made of any suitable material, such assteel, of sufficient strength to resist the pressure at which the gas isstored. This vessel is provided with a closure B of any suitable ordesired kind. The receptacle A is filled with a porous substance 0. Manydifferent substances may be used, such as asbestos, mineral wool,carbon, pumice-stone, and ceramic materials. One substance Which I findvery advantageous for this use is porous brick. For the best results thematerial should be of such a character that were it reduced to'powder itwould occupy from twenty to twenty-five per cent. only of the space itoccupies in its normal condition. In using porous brick of this kind orsimilar material I may form in the brick numerous small bores orperforations b for the purpose of facilitating the permeation of gasthrough the porous substance.

In preparing my receptacle for the storage of the gas in compressed formI saturate the porous substance with some solvent of the gas-as, forinstance, in storing acetylene gas I would saturate the porous substancewith acetone.

By saturated I mean that the amount of solvent used must be such thatthe danger from liquid expansion is avoided.

If the gas is to be charged under a pressure sufficient to liquefyit, itis forced into the re ceptacle by a suitable apparatus until theliquefying pressure is reached. The liquefied The gas will thencirculate through the pores' of the filling material, come in contactwith the solvent liquid, and be absorbed thereby.

By this apparatus explosive or inflammable gases of any kind may bestored without danger from explosion. The explosion will be confined tothe inconsiderable amount stored in one, or at most in few, of the cellsand would not be communicated to the body of stored gas. It isparticularly useful in the storing of acetylene gas either in itscompressed form or as a liquid or dissolved in a suitable solvent.

It is desirable that the filling substance be an integral mass; but Imay employ a number of blocks of the porous material and completely fillthe receptacle with the same, or I may partly till the receptacle withblocks and pack them round With fibrous or granular filling.

IVhat I claim, and desire to secure by Letters Patent, is

1. An apparatus for storing gas consisting of a receptacle filled With aporous substance, such porous substance being saturated with a solventof the gas to be stored, substantially "as described.

2. An apparatus for storing gas consisting of a receptacle filled Withporous material molded to fit the interiorthereof,substantially asdescribed.
